3/8" Nut Implanted PCB Stand Off

Added a leg beneath sculler1956's V2 PCB standoffs designed to have a 3/8" nut implanted during a print pause programmed at a height of 1cm. *The height of the nut cavity was extended beyond the hardware's actual height to prevent possible damage of the extrusion nozzle bumping into the nut.*

Before printing, add a print pause around 1cm. For me, printing at a .1mm resolution, this came around layer 103.

To do this in Cura, at the top click 'Extensions' -> 'Post Processing' -> 'Modify Gcode'.
Click the "Add A Script" button.
Select "Pause at height".

It can be a tight squeeze to get the nut seated. I found it best to partially thread in a bolt and wiggle the nut down into place.
